b) the total variance in any other way.
2. Draw conclusions.

Task 7
1.Po data applications make 15-20 selection of commercial banks. View sample selection method and algorithm selection, define yourself.
2. To calculate the total sample formed:

B) average and marginal sampling error (P = 0.954).
3.Opredelite required volume of sample, in which the margin of error is 2.5% less than obtained in n. 2 size.
4.Sformiruyte new custom set of volume calculated in step 3.
5. For the newly formed calculate the total sample:
A) The average volume of deposits of citizens.
B) average and marginal sampling error (P = 0.954).
B) The interval in which the general average;
D) range in which the total amount of deposits of citizens in all the banks in the population.
6.Vychislite the population characteristics and compare them with the results obtained on the basis of sample survey.

Task 8
To examine the relationship between profit and the amount of investments in securities of 30 commercial banks:
A) Draw a connection between the studied traits graphically;
B) build the regression equation for the grouped data .........

Task 9
To examine the relationship between profit, volume of investments in securities and credit investments of commercial banks of the Russian Federation 15-20 (Table application):
1. Determine the performance and features of a factor. Please rate from an economic point of view, the importance of the factors and the sequence of their inclusion in the regression equation;
2. Determine the shape of the correlation equation and justify his choice;
3. the initial data, build graphs of resultant variable with each factor. Consider the nature of the relationship; ..........

Task 10
According to the statistical yearbook of any, do the following:
1. Select the number of speakers interval consisting of the levels of absolute values \u200b\u200bfor 10 consecutive periods (months, years, quarters, and so on. D.).
2. graphically dynamic series using statistical curve.
3. According to this number, calculate the absolute and relative performance indicators. State the results of the calculations in a tabular format and analyze them.
4. Calculate the average dynamics and analyze them.
5. Smooth the number of speakers using the moving average and analytical alignment. Estimated levels apply to the schedule, built in step 2. Draw conclusions about the nature of the trends discussed a number of dynamics.

Task 11
According to the monthly magazine "Statistical Review" Goskomstat, periodicals or internet sources:
1. Build a one-dimensional series of speakers monthly level in 2-3 years;
2. graphically raw data of your options and make a visual analysis;
3. Check the starting number of speakers for the presence of any known trends by you; 4. Check the number of speakers on the availability of seasonal ingredients. Determine the seasonality indices by constant mean and the analytical method of alignment in a straight line .....

Activity 12
According to the table the application of the turnover and the volume of sales of goods in the markets of the city for three products for three months:
1. Calculate the individual chain price indexes.
2. Calculate the combined chain price indexes, turnover and volume of goods sold.
3. Check the calculation of composite indices, using their relationship.
4. Calculate the price indices consolidated basis with constant and variable weights.
5. calculate the composite price indices in the middle of the harmonic form.
